XSD - Miscellaneous Data Types

---

XSD has a few other important data types, such as Boolean, binary, and anyURI.

<xs:boolean> data type

The <xs:boolean> data type is used to represent true, false, 1 (for true) or 0 (for false) value.

<xs:boolean> Example

Element declaration in XSD −

<xs:element name = "pass" type = "xs:boolean"/>

Element usage in XML −

<pass>false</pass>

Binary data types

The Binary data types are used to represent binary values. Two binary types are common in use.

• base64Binary − represents base64 encoded binary data

• hexBinary − represents hexadecimal encoded binary data

<xs:hexbinary> Example

Element declaration in XSD −

<xs:element name = "blob" type = "xs:hexBinary"/>

Element usage in XML −

<blob>9FEEF</blob>

<xs:anyURI> data type

The <xs:anyURI> data type is used to represent URI.

<xs:anyURI> Example

Element declaration in XSD −

<xs:attribute name = "resource" type = "xs:anyURI"/>

Element usage in XML −

<image resource = "http://www.tutorialspoint.com/images/smiley.jpg" />

Numeric Data Types

Following is the list of commonly used numeric data types.

S.No.	Name & Description
1.	byte A signed 8 bit integer
2.	decimal A decimal value
3.	int A signed 32 bit integer
4.	integer An integer value
5.	long A signed 64 bit integer
6.	negativeInteger An integer having only negative values (..,-2,-1)
7.	nonNegativeInteger An integer having only non-negative values (0,1,2,..)
8.	nonPositiveInteger An integer having only non-positive values (..,-2,-1,0)
9.	positiveInteger An integer having only positive values (1,2,..)
10.	short A signed 16 bit integer
11.	unsignedLong An unsigned 64 bit integer
12.	unsignedInt An unsigned 32 bit integer
13.	unsignedShort An unsigned 16 bit integer
14.	unsignedByte An unsigned 8 bit integer

Restrictions

Following types of restrictions can be used with Miscellaneous data types except on boolean data type −

• enumeration
• length
• maxLength
• minLength
• pattern
• whiteSpace
